Tofall'wrlwm t ma concern: i Y d Be it known t at- I, HORACE Bv. FAY, a citizen of the United States, and a resident 'of Wlloughby, Ohio, county of Lake, 'and State of Ohio, have invented anew andv useful Improvement in Axles, of which the vfollowing is( a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, soV as Ato distinguish Uit from other inventions.

The present invention, relating, as indicated, to axle construction, is particularly concerned with an axle of the type` commonly known as an internalv drive axle, in which the load is supported upon one mem- Aber designed particularly for that purpose,

and the'drive is communicated to the wheels through other members, whichare supported upon the load-carrying member. One

vobject of the present invention is to provide an axle of this type4 which is 'of simple vconstruction and of greater strength than 'those now Oenerall f in use. To the accomplishment of `the foregoing and related ends, said invention, then, consists of the rmeans hereinafter fully described and particularly pointed out in the claims. Y

The yannexed drawing and the following description set forth in detail certaincinech- 'anism embodying the invention, vsu'chgdisclosed means constituting, however, butrgone of various mechanical forms in which the principleof the linvention may be used.

'In said annexed drawing Figure 1 is applan view partially in section of my improved axle; Fig. 2 is a front ele,-v vation of the same showing the engagement between vthe load-carrying member and the driving members; and Fig. 8 is a section on the line 3 3, Fig. 2.

Referring now to Fig. 1, in which the general arrangement of parts is shown, there being a load-supporting axle 1 on the ends of which may be mounted the wheels of the vehicle, although these are not shown in the drawings, as the general construction of such an axle is of course well known. Behind this load-carrying axle 1 is mounted the driving axle consisting` of shafts 2 operating from a drivingshaft 3 at right angles thereto. The shafts 2 are suitably mounted in a tubular casing 4; fitting into a central inclosing casing 5, which incloses ythe inner ends of the shafts 2 and also the differential kmechanism 6 between the andthe axle It has been founddesirable in internalv drive axles to mount the ydriving load-supporting member, ,which is nthe c'o'ii-v struction followed in myimprov'edl 4 e.w

. It has also been found'that r'aiid driving Shaft.. 3

,members and the differential cheaper 'load-supporting member be made from a tubular housnig'thanrfroin' a fthe method of engagementfbetweeii member andthe ydifferentialleasing. vThis vconstruction is indicated .in,Fi`g's. V2faii'tl""3,

from which it 'will be seen that the `(,:eiitiial portion of the housing is provided with but one flange of any depth, this Bange Se'xtend ingdownward toward the front` ofthe differentialcasing. There is, however, no coii- ,Y

tact between either the front iiangef'offftlie housing or the narrow rear flange `9,12:OthfQof them being spaced fromV the -casingat v'all points. Mounted Within ,the housing, "between the flanges 7 and.. 8, is a'plate K10 :curved to fitthe inside ofthe centra k' p/,jru tion of the housing andqsecured thereto lby a 'pluralityf of Y,fastening yfdeveicesgsiich, as rivets v11.. Two;ofihesfuiinapiaas are used, one` against the topiV andorre against the bottoin'of the housing, and the lfilling plate when mounted in. ppsitionjsfacedDoif to providey a smooth curved surface, against which may be received a simil-ar part 12 formed on the differential casing. The dif-y.

ferential casing formed on this extending portion 12-is also formed with a smooth,

curved surface adapted to engage snugly against the inner surface of the filling blocks 10, and for convenience of assembly and tightness the outer face of this projecting portion 12 on the casing may be machined to provide a tight fit against the filling plates `10. When' the differential casing is mounted in position within the enlarged central portion of the housing it is secured thereto by means of a` plurality of radial bolts 13 passed throughsuitable holes drilled in the housing and in the filling plates 10 and tapped into the extending portion 12 on the casingE Y two parts of the entire axle, that is, the loadcarrying member and the casing and tubes which carry the driving parts.

Other modes of applying the principle of Ymy invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provvided the means stated by any ofthe following claims orv the equivalent of such stated means be employed. I therefore particularlyV point out and distinctly claim as my invention l. In a device of the character described,

' the combination of a tubular axle having copies of 'this patent may be Acriminali fer an enlarged portion intermediate its ends provided with alined openings, a gear casing mounted on one side of said axle and y extending into such openings, and fastening means extending through said casing and the top and bottom of such enlarged portions of said housing, said means securing Vsaid casing firmly to said housing.

2. Ina device of the character described, ythe combination of a tubular axle having A an enlarged portion intermediate its ends provided with alined openings, a gear casing mounted on one side of said axle and extending into such openings, filling blocks mounted within such enlarged portion of said axle, and adapted to receive said casing thereon, andV fastening means extending Vthrough said axle, said filling blocks and said casing, said means securing the same together.

'3. In a device of the character described, theV combination of ia tubular axle yhaving an enlarged portion intermediate its. ends provided with alined'concentric openings, a

gear casing mounted on one side of said axle and extending into such openings, filling blocks mounted within such enlarged portion of said axle, an extending portion on said casing adapted to fit snugly within said filling blocks, and means adapted to secure said casing in such engagement.

4. In a device of the character described, the combination of a tubular axle having an enlarged portion intermediate its ends provided with an opening in one face thereof, a gear casing mounted on oneside of said axle and extending into such opening, and fastening means extending through said axle in the pla-ne of the greatest transverse dimension thereof, said means engaging said casing and securing lthe same rmly to said axle. y

5. In a device of the character described, the combination of a tubular axle having an enlarged portion intermediate Vits ends provided with alined openings in opposite sides thereof, la differential carrying member mounted at one side of said axle and extending into said openings, and fastening means i extending through said axle and engagingy such carrying member, said means lying normal to the Vplane of the differential in said member.

6. In a device of the character described,-

the combination of a tubular axle having an enlarged portion intermediate its ends yprovided with alined openings in opposite sides thereof, a dierential carrying member extending into said openings and lying in spaced relation within said tubular axle,

filling means interposed between said axle and carrying member, and fastening means engaging said axle, filling means and carry ing member and securingthe saine rigidly together.
